Resize Image for YouTube | MiniPx — Free, Fast & Private
YouTube has specific image sizes for thumbnails, channel banners, and watermarks. Using the correct dimensions ensures your images display sharp and uncropped across desktop, mobile, and TV screens.
Key YouTube sizes: Thumbnail — 1280x720px (16:9, minimum 640px wide). Channel banner — 2560x1440px (safe area: 1546x423px center). Profile picture — 800x800px. Video watermark — 150x150px (appears as branding in corner).
Thumbnails are the most important image on YouTube. A sharp, well-composed 1280x720 thumbnail at under 2MB drives clicks — though Google's current guidance now recommends up to 3840x2160, a shift the YouTube thumbnail size guide unpacks in full. MiniPx resizes and compresses in one step — hit the right dimensions while keeping file size manageable. If your source frame is smaller than 1280px, upscale it to 4K-class resolution first so YouTube's re-compression has a sharp master to work from.
Channel banners are tricky because YouTube displays different crops on different devices. The full 2560x1440 is shown on TV, but mobile shows only the center 1546x423 strip. Keep text and logos in the safe area.
MiniPx handles all YouTube image needs without uploading your images to any server. Resize, compress, and download — all in your browser.
